分析小水电站主接线可靠性的一种方法

A Method of Reliability Analysis for Main Wiring Diagram of Small Hgdropowers

结合＂设计规范＂和仙人陂水电站实际，拟定四个主接线方案，应用可靠性数学原理，整理出一种主接线可靠性分析法，对四个方案建立数学模型，计算出各方案的系统可用率、强迫停运率、站用电强迫停运率．结果各方案可靠性相差甚小．以量定性可减小通常定性分析的主观性．

This paper contives four schemes of main wiring diagram,in accordance with the design specifications and the reality of a hydropower station.By using theory of relibility mathematics,we can conclude the method of relibility analysis.And by constituting four mathematical models work out the main target.With quantitative analysis instead of qualitative analysis,decreased subjectivity of generally qualitative analysis.
